A near-infrared fluorescent probe for imaging peroxynitrite levels in paw edema mice and drug evaluation

Chem Commun (Camb). 2024 Jun 25;60(52):6675-6678. doi: 10.1039/d4cc01562b.

Abstract

A near-infrared fluorescent probe (TX-P) for detecting peroxynitrite is constructed. The probe has a near-infrared emission (725 nm), large Stokes shift (125 nm) and excellent sensitivity and selectivity. In addition, TX-P can be used to visualize ONOO- in living cells, image ONOO- in paw edema mice and evaluate anti-inflammatory drugs.
